How to Select Anesthesia Equipment 

Respiration 

The anesthesia machine you select is dependent on 

a couple of parameters. Ask yourself the following 

questions: 

• How many animals are you working with 

• What species you are working with 

• Do you want a mobile system or table top system 

Multiple Animal Systems 

We only offer one system that is suitable for 

simultaneous multiple animal anesthesia delivery. It 

is our Multi-Station Research Anesthesia System. 

There are 3 models available for either 2, 4 or 6 

animals delivery. see page F33 for complete details. 

Single Animal Systems 

We offer a variety of single animal anesthesia 

machines. We offer both non-rebreathing and 

rebreathing systems. Each type is available in either 

a mobile or table top model, see below. 

Non-Rebreathing vs. Rebreathing Systems 

If you are working with animals under 4.5 kg (10 lbs) 

you can use a non-rebreathing system. If you are 

working with animals over 4.5 kg (10 lbs) you will 

need a rebreathing system. 

A non-rebreathing system takes the exhaled gas and 

directs it to a scavenging system. This system 

removes any leftover anesthetic agent from the gas 

so it is safe to release to the environment. Smaller 

animals have smaller respiratory capacities and 

therefore very little anesthetic agent is wasted. 

On the other hand, larger animals breathe larger 

volumes of gas and require more anesthetic agent. The 

advantage of a rebreathing system is that it takes the 

exhaled gas from the animal and recirculates it. A 

device scrubs the waste CO 2 from the gas and redirects 

the cleaned gas back to the inhalation circuit. This 

permits the system to reclaim the exhaled anesthetic 

agent and recirculate it to the animal. This recirculation 

process substantially reduces the amount of anesthetic 

agent used during the procedure. 


Non-Rebreathing Systems 

These systems are for use with animals 4.5 kg (10 lbs) or less. You can 

select from a variety of anesthesia machines. They are listed below and 

are classified as suitable for mobile use or for table top use only. Please 

note that the CDS 9000, Anesthesia Machines may also be used for 

non-rebreathing applications, but they are less economical if you only 

need a non-rebreathing system. They are listed under the Rebreathing 

Systems to the right.

Evacuation System Selection Guide 

Evacuation Systems are necessary when waste gas from the animal still contains anesthetic agents. It must 

be removed from the exhausted gas before it can be released into the environment. What kind of evacuation

Evacuation System Selection Guide (continued) 

Evacuation System Selection Guide 

Harvard Apparatus offers five basic evacuation/scavenging systems that work with our anesthesia setups. A brief description of these systems 

and their components are listed below. Three of the systems have multiple configurations based on your anesthesia setup. The basic 

components are the same, just connections and adapters change with each configuration. 

F/Air Evacuation 

This evacuation system is a simple 

and economical way of removing 

anesthetic gases. The active 

charcoal in the canister removes 

the waste gas. The used canister 

can be tossed in the trash for 

disposal. See page F34 for 

complete details. 

Fluovac System 

The Fluovac Systems actively 

scavenges anesthetic waste and 

does not require venting to a 

hood. It uses the Fluosorber 

Canisters, which when full, can be 

disposed of in the regular trash. 

See page F46 for complete details.

Why Use an Anesthetic Manifold 

Manifolds allow the use of both an anesthetizing box and a mask. It 

permits the research to direct the flow of gas to where they need it. The 

anesthetizing box can be used to initially anesthetize the animal and then 

the mask can maintain the anesthetized state during procedures. One side 

of the manifold directs the fresh gas to the animal, while the other directs 

the waste gas collection. 

Harvard Apparatus does not suggest using manifolds to anesthetize 

multiple animals simultaneously. PLEASE NOTE, with a manifold, the 

amount of agent flowing into each port cannot be controlled – for 

individual control to multiple animals, see the Multi-Station Research 

System on page F33 of this catalog.

Anesthesia and Evacuation Systems 

PY2 72-3025 

(Vaporizer 

not included) 

Multi-Station 

Research Anesthesia 

System 

• Anesthesia delivery 

system designed 

specifically for research 

• Multiple, individually 

controlled stations in 

a single unit 

• Unique rodent circuit, 

mask and diaphragm 

system for safe, 

effective anesthetic 

agent delivery 

• Use with lab animal 

evacuation system 

The Multi-Station Research Anesthesia System is the latest technology for 

rodent and small animal anesthesia. The multi-station unit offers a base unit 

with multiple stations each individually controlled. The master flowmeter and 

auxiliary flowmeters all receive the same gas supply. The master flowmeter 

combined with an anesthetic vaporizer, Series T3, see page F36, are used to 

set the maximum percentage of anesthetic agent delivered to each station. 

Using the auxiliary flowmeters, the percentage of anesthetic agent can be 

diluted using the fresh gas supply from the auxiliary flowmeter. Using an 

easy-to-follow flow chart, each individual station can deliver a different 

percentage of anesthetic agent as needed, without effecting any other station. 

The unique rodent circuit, PY2 72-3026 features a coaxial tube used in 

conjunction with a mask. By placing the animal’s nose into the mask 

diaphragm, it receives the delivered gas/anesthetic agent mixture. Three 

different size diaphragms are available. The waste gas exhaled from the 

animal and any unused gas delivered by the anesthesia machine, is pulled 

around the inner cone through the outside hose of the Rodent Circuit. This 

waste gas can be removed from the breathing circuit using either in-house 

vacuum or the Lab Animal Evacuation system, PY2 72-3066. The unit is a 

simple to use, safe and effective anesthetic delivery and evacuation system 

designed specifically for laboratory research use. 

The Multi-station Research Anesthesia system is available with two (2), four 

(4), or six (6) stations. It is supplied with an operational manual, station hoses, 

rodent circuits which include, a mask, hose and a medium diaphragm and 

endcaps. A vaporizer, see page F36, and evacuation system must be 

purchased separately. 

An alternative to the Lab Animal Evacuation system is to connect each rodent 

circuit exhaust/exhalation line to it’s own F-Air Filter canister, see page F34.

Evacuation System 

Lab Animal Evacuation System 

The Multi-Station Evacuation System was designed for those facilities that 

do not have a built-in evacuation system or a fume hood is not available. The 

waste gas from the system may be vented to a 2 inch outside line or pulled 

through activated charcoal so that the air can be recirculated in to the room. 

When using the filtration system, the activated charcoal must be changed on 

a regular basis, to maintain it’s effectiveness. Typically, 8 to 10 hours of 

anesthesia delivery can be performed for each new supply of charcoal. The lab 

evacuation system, will accommodate waste gas supply from 1 to 6 stations.

NOTE: When using in-house suction, a scavenger interface valve must be used when operating 

more than one station, to reduce the pull of air.

The Anesthetic Evacuation System (AES) will safely and actively remove waste 

gas associated with everyday inhalation anesthesia. It can be mounted on the 

pole of the CDS 9000 or Vaporstick, see pages F31 to F32. It can also be used 

as a freestanding unit and simply placed on the benchtop. Two standard 19 mm 

(0.75 inch) inlets and one exhaust port allows easy hook-up to existing 

equipment. A 12 foot grounded electrical cord and lightweight tubing, allows 

for machine maneuverability. 

The waste gas from the pop-off valve on most rebreathing anesthesia machines 

is collected by passive flow to the AES. This allows for safe operation of the 

anesthesia machine with little or no vacuum exposure. Using a push blower, 

the AES actively removes the waste gas from the unit. The blower has the 

capacity of moving 12 cubic feet/minute through up to 150 feet of tubing to an 

outside vent or fume hood. The on/off switch illuminates a green light when the 

unit is activated. The ‘on’ light assures the operator that the unit is functioning. 

The Anesthetic Evacuation System includes a 3 inch and a 10 foot length of 

19 mm ID hose and a 12.5 mm (0.5 inch) PVC Adapter. Additional lengths of 

tubing may be required and are available as an option along with an adapter 

to interconnect the 19 mm outlet tubing. An optional outlet line ceiling plate 

is available when connection to an outside wall is not convenient. Unit is 

14 in. tall, 5 in. in diameter and weighs 5 lbs.

PY2 72-7108 

COAX Breathing Device 

• For rodents, guinea pigs, and birds 

• Durable – constructed of Delrin 

This COAX breathing device is a precisely machined apparatus which maintains 

the surgical plane. The fresh anesthetic gas enters the side port and then 

passes to the nose cone. At this point the anesthetic gas is mixed with the 

patient’s respiration and then passes out through a ball check valve to the 

gas outlet for scavenging. The positive pressure from the oxygen source and 

the patient’s respiration lifts the precision ball valve for scavenging. A #10 

balloon acts as a diaphragm or breathing bag. 

The COAX is available as a free standing unit or mounted to a durable HDPE 

procedure table. This table includes metal strips to hold heating pads in place 

and points for tie downs. This unit is supplied with face masks (2 rat and 

2 mouse), height adjustment collars and 10 ft. of 0.25 in ID tubing. The unit 

measures H x W x L, 2 x 40.6 x 31.8 cm (4 x 16 x 12-1/2 in).

Developed in conjunction with leading research facilities, the Rodent Circuit 

is the most effective, user-friendly, mask for rodents. Available with 3 different 

size diaphragms, the mask easily fits most rodents. With the use of a C-Pram 

circuit shown above, the mask is designed to deliver and evacuate the gas 

through one tube. Traditionally, the open mask system has caused problems 

because of the contamination of waste gas to the staff and the patient 

rebreathing CO 2 

. These problems are avoided with the Rodent Circuit and mask 

design. When combined with in-house suction or the Lab Animal Evacuation 

System or F/Air canister, see page F34, there is minimal risk of untoward 

anesthetic agent exposure for the researcher. Inlet tubing: 6.25 mm (0.25 in) 

ID, silicone tubing. Outlet from rodent circuit is a 22 mm (0.866 in) respiratory 

fitting. Respiratory Adapters are available to connect the rodent circuit outlet 

to tubing of various sizes from 6 to 15 mm ID, see page F38.

Rebreathing Anesthesia Circuit 

Universal Rebreathing Anesthesia F-Circuit 

The Universal F-circuit is a rebreathing circuit that can be used on small animals 

up to 200 lbs. Rebreathing circuits allow the animal to rebreathe exhaled and 

excess vaporized anesthetic agent which have circulated through a CO 2 absorber 

system thus reducing the amount of anesthetic agent used. The unique single

2) reduces the clutter around the animal and 3) takes the weight off the end 

of the endotracheal tube. The tube within a tube design allows heat and 

moisture to be retained in the circuit, which helps to maintain body temperature 

and recover the patient more quickly.

Fluovac System, IMS Fluosorber 

and Accessories 

IMS Fluosorber 

Fluovac System PY2 34-0415 

The Fluosorber consists of a canister 

containing activated carbon, which 

absorbs anesthetic gas extremely 

efficiently. 

It is used with the Fluovac to scavenge 

anesthetic waste from the working 

environment, and is quickly and 

simply attached to the Fluovac unit. 

The Fluosorber’s capacity to scavenge 

is measured by weight: Simply 

pre-weigh canister and change once 

it has increased 200 grams. During 

manufacturing each Fluosorber is tested to ensure an air flow of 60 liters per 

minute with a flow resistance not exceeding 2.0 cmH 2O. When exhausted, 

the Fluosorber is sealed in the special bags provided and can then be 

completely incinerated. Supplied in cases of 6 canisters. 

Respiration 



• Absorbs anesthetic vapors from the work area, 

protecting personnel from exposure 

• Allows optimal access to the animal particularly 

important when carrying out close-up or micro 

surgery 

• A self-contained, portable unit requiring no extra 

ducting or ventilation 

• Three different size masks available 

• Incorporates a special double mask which supplies 

the anesthetic and scavenges excess vapors 

simultaneously 

• Requires minimal maintenance 

• Easy to use: simply connect to your vaporizer 

system and insert a Fluosorber canister 

• Each Fluovac is supplied with a size 1-Double mask 

The Fluovac Systems combines small animal anesthesia with operator 

safety. Fluosorber canisters must be ordered separately, see to the right.

a tube mount to vent exhaust gases 

such as nitrous oxide (Note: It is not 

necessary to vent if only anesthetic 

agent is used as the Fluovac with the Fluosorber canister, removes anesthetic 

gas from the atmosphere most effectively). Suitable tube for venting is the 

cuffed plastic tubing, see PY2 34-0426 on page F53.

Gas Flow Directors 

An effective yet simple method of 

eliminating the Connector Set 

from the IMS Fluovac system. 

Directs the flow of gas to either or 

both double rodent mask simply 

by turning the knob. 

Directavalves 

Gas flow can be sent in one of two 

directions by simply turning a small 

valve on top of the assembly. 

Fluovac Isolator 

Valve 

A most useful addition to our gas 

scavenging range, the valve redirects 

gas from the FLUOVAC mask when 

out of use for short periods. The 

advantage is that neither the 

Vaporizer setting nor the flowmeter 

setting have to be altered when an animal is removed from the mask thus 

saving time having to reset the previous settings. 

Also, if the gas flow has inadvertently been set a little high then it could 

overcome the scavenging action at the mask when an animal is removed - the 

use of the valve prevents contamination of the area by stopping the gas 

reaching the mask. 

The valve is activated by the push/pull control knob to the indicated setting. 

In use the gas supply and scavenged gas flow through specially machined 

channels in the valve. In the isolation mode the gas flow from the vaporizer 

is directed into the scavenged gas flow while simultaneously opening a 

channel to outside air which is sucked into the mask by the scavenging effect 

thus also clearing traces of anesthetic gas from the mask. 

The units are easily fitted into existing masks by the user - full instructions 

are included. Please state the size of the mask to be modified as Size 1 has 

a smaller bore Crystaflex tube than 2 & 3.

anesthetic gas and is also scavenged. 

The patient is kept up to the front of 

the tube with a holding bar. When the animal is anesthetized it is taken out 

of the tube, the mask is unplugged and the animal is positioned at the 

mask–a very quick and easy procedure.

Fluovac Anesthetizing Chamber 

with Gas Scavenging System 

Further enhance the flexibility of your Fluovac system by the addition of a 

special anesthetizing chamber. No modifications to the existing Fluovac 

unit are necessary. 

The system provides a safe working environment for staff while minimizing 

stress to the animal. 

The crux of the system is the Directavalve, a valve which can control the flow 

of gases and vapors in either of two directions. Two Directavalves are used 

in the system. One is placed on the outlet tube mount of the Vaporizer, so that 

halothane can be directed to either the Fluovac masks or the anesthetizing 

chamber. The other is placed on the Fluosorber canister, so that Fluovac 

scavenges from the mask or chamber as required. 

The clear Perspex chamber has a 6mm inlet tube mount which enters the 

chamber under a false floor. Scavenging is via a tube mount with specially 

shaped air bleeds. These create a vortex in the chamber, optimizing the 

scavenging effect. 

Removal of the animal will cause some vapor to be released: this can be 

overcome by placing the chamber in a flow hood. 

Please note that there are two sizes available, the smaller designed is 

specifically for a single animals. 

NEW Portable Scavenged Anesthesia Table 

Harvard Apparatus have developed a simple easy to use portable scavenged 

anesthetic operating table for mice. Simply connect the anesthetic delivery 

tube to your anesthetic supply. Then connect the exhaust mount to your 

Fluovac scavenging system (22 mm bore scavenge tubing). This will give you 

an inexpensive, portable, down-draft operating table. Tables can also be 

created for Rats. Please ask for details.

For use in conjunction with the Fluovac. It is easy to use–simply plug a size 

one mask into the rear socket, turn on the Fluovac and gas supply. 

When the animal(s) are anesthetized the inner chamber slides forward 

allowing the gas supply to be diverted and the chamber scavenged. During 

this process fresh air is drawn into the inner chamber to help scavenge any 

residual anesthetic gas. 

The following sizes are the dimensions of the inner chamber only. Please
